i
Biology must remain the central academic lens

A Biology EE should focus on living organisms, biological systems, biological processes, or biological relationships. Even when the topic overlaps with another discipline, the argument should remain clearly biological.

BIOLOGY MUST DRIVE THE INVESTIGATION

Keep the Extended Essay Focused on Biological Theory and Life Processes

A strong Biology Extended Essay does more than describe a health issue, environmental problem, organism, or experiment. The essay should use biological concepts and evidence to investigate a focused question and develop a reasoned biological conclusion.

01

Biological Question

Establish a question that can be addressed through biological concepts, evidence, and analysis.

02

Biological Theory

Introduce relevant mechanisms, structures, processes, interactions, and biological principles.

03

Biological Evidence

Use appropriate observations, measurements, published evidence, or genuine investigation data.

04

Biological Conclusion

Answer the question using the biological evidence and reasoning developed in the essay.

BIOLOGY EE RESEARCH QUESTION

Build a Research Question That Allows Focused Biological Analysis

The research question determines what biological evidence the essay needs and which variables, organisms, processes, environments, treatments, datasets, or biological relationships should remain within scope.

01

Specific

Identify the biological relationship or process being investigated as precisely as possible.

02

Manageable

Keep organisms, variables, conditions, location, or datasets within a workable scope.

03

Analytical

Create room for interpretation, comparison, relationships, mechanisms, or evaluation.

04

Evidence-Based

Confirm that suitable biological evidence can realistically address the proposed question.

BIOLOGICAL RESEARCH AREAS

Write the Essay Around the Biology Required by Your Research Question

Biology EE topics can involve different levels of biological organization. The writing should therefore use concepts and terminology appropriate to the specific research question rather than forcing every Biology EE into the same structure.

C

Cell & Molecular Biology

Cellular processes, enzymes, membranes, metabolism, molecular interactions, and related biological mechanisms.

G

Genetics

Inheritance, gene expression, variation, populations, genetic relationships, and molecular evidence.

P

Physiology

Functional processes in plants, animals, microorganisms, or other biological systems.

E

Ecology

Populations, communities, ecosystems, environmental variables, distributions, and interactions.

EV

Evolution

Selection, adaptation, variation, phylogenetic patterns, and evolutionary processes.

M

Microbiology

Microbial growth, physiology, interactions, environmental responses, and biological processes.

BIOLOGICAL THEORY

Establish the Biology Needed to Understand the Investigation

Background sections should not become broad textbook summaries. Biological theory is most useful when it explains the mechanism or relationship that the later investigation, data, and discussion will examine.

01

Define Key Concepts

Introduce biological terminology and processes directly relevant to the question.

02

Explain Mechanisms

Show how relevant biological structures and processes are expected to operate.

03

Connect Variables

Explain biologically why a change in one factor may affect another.

04

Build Expectations

Use biological theory to establish scientifically reasoned expectations before analysing results.

BIOLOGICAL INVESTIGATION

Match the Investigation Method to the Research Question

The Biology EE method should generate or identify biological evidence capable of addressing the research question. The exact approach depends on the topic, available evidence, ethical requirements, safety constraints, and research design.

LAB

Experimental Investigation

Controlled biological investigations can examine the effect of a defined factor on a measurable response.

FIELD

Field Investigation

Ecological or environmental investigations can examine naturally occurring biological patterns and relationships.

DATA

Data-Based Investigation

Suitable existing biological datasets can be analysed when they allow genuine biological investigation.

LIT

Literature-Based Evidence

Published biological research can establish theory, provide evidence, and contextualize findings.

VARIABLES & BIOLOGICAL CONTROLS

Define the Factors That Shape the Investigation

In experimental and comparative biological investigations, the essay should make important variables clear. This helps explain what was changed, what was measured, what was controlled, and which biological factors could influence the results.

IV

Independent Variable

Define the factor deliberately changed or compared in the investigation.

DV

Dependent Variable

Define the biological response or outcome measured during the investigation.

CV

Controlled Variables

Explain important factors kept consistent to improve interpretability of results.

CF

Confounding Factors

Identify relevant uncontrolled influences that may affect observed biological patterns.

BIOLOGY EE METHODOLOGY

Explain How the Biological Evidence Was Obtained

Method writing should allow the reader to understand how the investigation generated relevant biological evidence. It should explain the important procedural decisions without filling the essay with unnecessary routine detail.

01

Research Design

Explain why the chosen investigation can address the research question.

02

Sampling

Describe relevant sample selection, replication, sample size, or biological units.

03

Measurement

Define how biological variables were observed, quantified, or classified.

04

Controls

Explain procedures used to reduce unwanted variation or alternative explanations.

BIOLOGICAL DATA

Turn Biological Measurements Into Evidence for the Research Question

Data should move through a clear analytical chain. Raw observations alone do not answer the research question. The essay should organize, process, analyse, and interpret the data using methods appropriate to the biological investigation.

RAW DATA → PROCESSING → STATISTICS → BIOLOGICAL INTERPRETATION

Build a Clear Evidence Chain From Measurement to Conclusion

Our Biology EE writing service can organize supplied genuine data, calculations, statistics, graphs, observations, and biological interpretation so each analytical step contributes directly to the research question.

Raw observations Processed data Descriptive statistics Statistical tests Graphs Tables Patterns Biological interpretation
TABLES, GRAPHS & FIGURES

Present Biological Evidence in a Form That Supports Analysis

Tables and figures should make biological patterns easier to identify. Clear titles, labels, units, legends, error information, and references in the text help integrate visual evidence into the essay’s argument.

T

Tables

Organize relevant raw or processed values without overwhelming the main discussion.

G

Graphs

Show trends, differences, distributions, relationships, or biological responses clearly.

F

Figures

Use relevant diagrams or images where they add genuine biological information.

I

Interpretation

Explain what each important pattern means biologically for the question.

STATISTICAL ANALYSIS

Use Statistics to Test Biological Patterns Where Appropriate

Statistical analysis should answer a biological purpose. The essay should explain why a statistical method suits the data, what its result indicates, and how the result affects the biological interpretation.

01

Describe

Summarize central tendency, spread, variation, frequency, or other useful data features.

02

Compare

Analyse biological differences between treatments, groups, populations, or conditions.

03

Test

Apply suitable inferential or relationship tests when justified by the data.

04

Interpret

Translate statistical output into cautious and biologically meaningful conclusions.

BIOLOGICAL INTERPRETATION

Explain Why the Observed Pattern Makes Biological Sense

A result section states what the data show. Biological interpretation explains what those findings may mean, which biological mechanisms could account for them, and how they relate to the theory and sources introduced earlier.

01

Identify the Pattern

State the important relationship, difference, trend, or response visible in the evidence.

02

Explain the Mechanism

Use biological theory to explain why that pattern may have occurred.

03

Compare With Research

Relate findings to relevant published biological evidence where useful.

04

Qualify the Claim

Avoid claiming more than the design and evidence can demonstrate.

BIOLOGY EE DISCUSSION

Connect Results, Biological Theory and Published Research

The discussion should move beyond repeating graphs. It can explain biological mechanisms, compare findings with relevant research, evaluate alternative explanations, examine unexpected patterns, and determine how strongly the evidence answers the research question.

01

Main Findings

Identify the results that matter most for answering the research question.

02

Biological Mechanism

Explain findings using relevant biological theory and processes.

03

Existing Evidence

Compare the investigation with credible published biological research where relevant.

04

Critical Judgment

Determine how confidently the available evidence answers the question.

VARIATION, ERROR & UNCERTAINTY

Evaluate the Sources of Variation That Affect Biological Results

Biological systems naturally vary, and measurements can introduce additional uncertainty. Evaluation becomes stronger when it distinguishes biological variation, measurement uncertainty, procedural limitations, sampling issues, and uncontrolled variables.

BV

Biological Variation

Consider natural differences between organisms, samples, populations, or biological responses.

MU

Measurement Uncertainty

Identify limits caused by instruments, measurement methods, resolution, or observation.

SV

Sampling Variation

Evaluate sample size, sample selection, representation, and replication.

CV

Confounding Variables

Discuss other biological or environmental factors that could affect the result.

CRITICAL EVALUATION

Evaluate Limitations by Their Effect on the Biological Conclusion

A useful evaluation does not simply list “human error.” It identifies specific weaknesses, explains how they may affect the evidence, considers the direction or importance of that effect, and proposes realistic improvements.

01

Identify

State the specific methodological or biological limitation clearly.

02

Explain Impact

Show how the limitation could affect the data or interpretation.

03

Judge Importance

Distinguish major threats to validity from relatively minor imperfections.

04

Improve

Suggest a practical change that directly addresses the identified limitation.

SCIENTIFIC SOURCES

Use Biological Literature to Build and Test the Essay’s Argument

Scientific sources can establish biological theory, support method choices, provide comparison data, explain mechanisms, and place the investigation within existing biological research. Source use should therefore contribute to analysis rather than appear only in the introduction.

01

Biological Theory

Source mechanisms, processes, definitions, and established biological knowledge.

02

Research Studies

Use relevant scientific studies to contextualize and compare findings.

03

Data Sources

Cite external biological datasets, databases, measurements, or published values accurately.

04

References

Keep in-text citations and bibliography entries consistent with the required style.

!
BIOLOGICAL ETHICS & SAFETY

Use a Research Method That Is Safe, Ethical and Suitable

Biology investigations can involve living organisms, biological samples, environmental fieldwork, laboratory procedures, or substances requiring additional care. Research design should respect appropriate ethical and safety limits.

Our writing and editing service works from genuine research material supplied for the project. We do not present fabricated experiments, invented observations, or false biological measurements as if they were genuinely collected data.

BIOLOGY EE CONCLUSION

Answer the Research Question From the Biological Evidence Developed

The conclusion should bring the investigation together. It should answer the research question, synthesize the strongest findings, connect those findings with biological theory, and acknowledge important limitations that affect the certainty of the answer.

01

Answer

Respond directly to the original biological research question.

02

Evidence

Base the answer on the strongest analytical findings developed earlier.

03

Biology

Explain the result in terms of relevant biological mechanisms or relationships.

04

Qualification

State important limitations affecting the certainty or scope of the conclusion.

4,000 maximum words
EXTENDED ESSAY WORD LIMIT

Keep the Biology Extended Essay Within the 4,000-Word Maximum

Word-count editing can remove excessive background theory, duplicated methodology, repeated description of graphs, unnecessary definitions, and discussion that does not contribute to the research question. The space should remain focused on biological analysis, discussion, and evaluation.

CURRENT EE VS FIRST-ASSESSMENT-2027 EE

Write for the Extended Essay Criteria Used in Your Examination Session

The Extended Essay assessment model changes from first assessment in May 2027. Biology remains available through the subject-focused pathway, but the assessment criteria are reorganized. The examination session should therefore be confirmed before final editing.

CURRENT CURRENT ASSESSMENT FRAMEWORK

Five Current Criteria

  • Focus and method
  • Knowledge and understanding
  • Critical thinking
  • Presentation
  • Engagement
2027+ FIRST ASSESSMENT MAY 2027

Five Redesigned Criteria

  • Framework for the essay
  • Knowledge and understanding
  • Analysis and line of argument
  • Discussion and evaluation
  • Reflection
FIRST-ASSESSMENT-2027 CRITERIA

Build the Biology EE Around the Redesigned Assessment Model

Under the redesigned framework, the essay still needs a focused research question, appropriate biological knowledge, a sustained analytical argument, critical discussion, evaluation, and meaningful reflection. The biological investigation should remain coherent across the whole essay.

A

Framework for the Essay

Research question, research methods, organization, and subject-appropriate conventions.

B

Knowledge & Understanding

Biological theory, terminology, concepts, processes, and subject knowledge.

C

Analysis & Line of Argument

CURRENT REQUIREMENTS & RESPONSIBLE USE

Keep the Extended Essay Clearly Biological and Research-Based

A Biology Extended Essay should incorporate biological theory and emphasize biology as the study of living organisms and life processes. Topics that overlap with other disciplines should still be treated through a clearly biological approach.

Biological investigations should use methods appropriate to the research question. Where laboratory or field research is involved, safety and ethical considerations must be taken seriously.

The Extended Essay has an upper limit of 4,000 words. The essay should therefore prioritize biological analysis, discussion, evaluation, and research that directly contribute to the question.

The redesigned EE has its first assessment in May 2027 and uses the criteria Framework for the Essay, Knowledge and Understanding, Analysis and Line of Argument, Discussion and Evaluation, and Reflection.

Students remain responsible for genuine research activity, authentic biological data, ethical and safe practices, accurate source attribution, and compliance with school requirements.
